A prospective, randomized, controlled, multicentre trial for secondary prevention in patients with chronic coronary syndrome using a smartphone application for digital therapy: the CHANGE study protocol.

Aims: Coronary artery disease (CAD) remains the leading cause of death worldwide. 'Stable' CAD is a chronic progressive condition, which recent European guidelines recommend referring to as 'chronic coronary syndrome' (CCS). Despite therapeutic advances, morbidity and mortality among patients with CCS remain high.

Intracranial haemorrhage in adult patients on venoarterial extracorporeal membrane oxygenation.

Aims: Intracranial haemorrhage (ICH) is one of the most serious complications of adult patients treated with venoarterial extracorporeal membrane oxygenation (VA-ECMO) and is associated with increased morbidity and mortality. However, the prevalence and risk factors of ICH in this cohort are still insufficiently understood. We hypothesized that a considerable proportion of patients undergoing VA-ECMO support suffer from ICH and that specific risk factors are associated with the occurrence of ICH.

Percutaneous dilatational tracheotomy in high-risk ICU patients.

Background: Percutaneous dilatational tracheotomy (PDT) has become an established procedure in intensive care units (ICU). However, the safety of this method has been under debate given the growing number of critically ill patients with high bleeding risk receiving anticoagulation, dual antiplatelet therapy (DAPT) or even a combination of both, i.e.

AIM2 Stimulation Impairs Reendothelialization and Promotes the Development of Atherosclerosis in Mice.

Atherosclerosis has been shown to result from chronic inflammation caused by constitutive activation of the pattern recognition receptors (PRR), which are principle effectors of the innate immune system. PRR are present in the endosome or on the cellular membrane and can sense the aberrant release of nucleic acids, which is often a sign of acute or chronic cellular damage. Absent in melanoma 2 (AIM2) is a PRR that is expressed by vascular cells and specializes in detecting cytoplasmic double-stranded DNA (dsDNA).

MDA-5 activation by cytoplasmic double-stranded RNA impairs endothelial function and aggravates atherosclerosis.

Recent studies have highlighted the relevance of viral nucleic acid immunorecognition by pattern recognition receptors in atherogenesis. Melanoma differentiation associated gene 5 (MDA-5) belongs to the intracellular retinoic acid inducible gene-I like receptors and its activation promotes pro-inflammatory mechanisms. Here, we studied the effect of MDA-5 stimulation in vascular biology.

Proinflammatory Stimulation of Toll-Like Receptor 9 with High Dose CpG ODN 1826 Impairs Endothelial Regeneration and Promotes Atherosclerosis in Mice.

Background: Toll-like receptors (TLR) of the innate immune system have been closely linked with the development of atherosclerotic lesions. TLR9 is activated by unmethylated CpG motifs within ssDNA, but also by CpG motifs in nucleic acids released during vascular apoptosis and necrosis. The role of TLR9 in vascular disease remains controversial and we sought to investigate the effects of a proinflammatory TLR9 stimulation in mice.

Inflammatory response of human coronary artery endothelial cells to saturated long-chain fatty acids.

Saturated long-chain fatty acids (SFAs) exert unfavourable metabolic effects (lipotoxicity) and induce apoptotic cell death (lipoapoptosis) in certain cell-types. Their contribution to inflammatory cell responses is unclear. We studied the expression of 113 inflammatory genes in human coronary artery endothelial cells (hCAECs) and their regulation by SFAs and unsaturated long-chain fatty acids (UFAs).
